Hi,
thanks for your bug report. I have fixed this in git by documenting
the behaviour: If run() returns 0, items may still have transient
errors.
There's no way we could change the behavior of run().

Subject: [PATCH] Acquire: Document that items may have transient errors on
run() success
If run() succeeded, items may still have transient errors, like a
Not Found error.
Closes: #680997
